Ms. Martens, 36, was a single mother of two and a third-generation volunteer firefighter and emergency medical technician for the Ashby Fire Department.

Her Kia Sportage crossed into the path of a pickup truck and crashed near 1191 Ashby Road (Route 31) in Fitchburg around 10:30 a.m.

According to the RMV, Ms. Martens's license had been suspended since Sept. 9, 2012, for failing to pay a citation issued on June 25, 2012, in Fitchburg for a right-of-way intersection violation.

Also, her license was in a non-renewal status for outstanding E-ZPass fines and parking tickets in Somerville, the RMV said.

Justin Fournier had a valid Class D permit, which was issued in Sept., 2012, according to the RMV.

However, according to the RMV driver's manual that cites the rules of driving with a permit, permit operators must be accompanied by a licensed operator who occupies the passenger seat next to them, who is at least 21 years old, holds a valid driver's license from Massachusetts or another state and has at least one year of driving experience.

Worcester District Attorney Joseph D. Early Jr.'s office has not said who was driving at the time of the collision. The crash remains under investigation.

Ashby Fire Chief William T. Seymour Jr. said today the fire department requires firefighters have a driver's license, but it is not routinely checked.

The driver of the Chevrolet Silverado pickup that they collided with also served on the Ashby Fire Department for 15 years. Wayne F. Patenaude, 54, of Ashby, was in stable condition last night at UMass Memorial Medical Center in Worcester awaiting surgery on his right heel, which was crushed in the crash. His arm was also injured.
